Description
The Arduino Uno R3 is one of the most popular microcontroller boards used in electronics and programming education. It is based on the ATmega328P microcontroller and features a non-SMD (Through-Hole) version of the processor. This version is preferred by those who want to easily replace or troubleshoot the microcontroller as it uses standard pins instead of surface-mounted components. It offers an easy-to-use platform for building projects, with ample documentation and a large community supporting it. The Uno R3 also features multiple I/O options, communication protocols, and an integrated USB interface for programming and communication.
